Products Description

As the core fasteners of industrial connections, our Double-Ended Threaded Bolts adopt a hot forging + precision thread rolling process. Both ends can be customized with full thread (Full Thread) or partial thread (Partial Thread), which is suitable for mechanical equipment, pipeline flanges, mold positioning, building steel structures, and precision connection of electronic equipment. 45# steel (8.8 grade), 35CrMo (10.9 grade), or 304 stainless steel are selected, and they are certified by IATF 16949, ISO 9001, RoHS/REACH. M6-M100 metric and UNC/UNF imperial specifications are provided to ensure reliable connection under vibration, high pressure, and precision assembly scenarios.

Diverse Applications

Mechanical Connection

Double-ended studs are used to connect mechanical components such as motors, gears, and couplings, providing stable and reliable support for the smooth operation of machinery.

Pipeline Installation

Double-ended bolts are ideal for securing pipes and fittings, ensuring the stable connection of pipeline systems, and preventing leaks.

Mold Manufacturing

Double Lag Bolt precisely assembles mold components, helping maintain mold accuracy and dimensional stability.

Construction Structures

Double-ended threaded Studs are used in building structures such as steel frames and bridges, connecting structural components to ensure the overall stability and safety of constructions.

Electronic Device Assembly

Double-ended threaded Bolt securely mounts electronic components and enclosures, providing reliable support for electronic devices.

Application of Double-Ended Stud Bolt

Key Advantages

Double-ended thread design・Revolution in connection flexibility
1. Thread customization:
Full thread: Suitable for scenarios where full-length force is required (such as motor shaft fixing), thread density ≥6 threads/mm, tensile strength increased by 20%;
Partial thread: The light rod section reduces stress concentration (such as mold guide column connection), and the thread length can be customized as required (accounting for 20%-80% of the total length).
Precision guarantee: The thread rolling process achieves 6g level accuracy, the pitch error ≤±0.005mm, and is suitable for high-precision Double Threaded Bolts (such as Hegedus anti-loosening nuts).
